No BOM lines error

HI! I'm studying ADempiere if can be used in our company, just beginning actually. I would really appreciate it if you could help me with my queries.

Im trying to walk through the production process using Sistematika, but as I was about to manufacture, i encountered the "No BOM lines" error. I have already entered the BOM components, and i dont think i missed a step - what should i do to correct this?
